compression technology is the core strength of JPEG2000,
which is designed to meet the growing application needs not
addressed by the current JPEG standard. While offering state-of-the-art
compression, JPEG2000 also offers unprecedented access into
the image while still in compressed form. Thus, images can
be accessed, manipulated, edited, transmitted, and stored
in a minimal information form.
JPEG2000 supports a wide set of features,
achieving in a single file format what the original baseline
JPEG offers in 44 largely incompatible modes. JP2 is a feature-rich,
flexible format that is striving to be an open standard by
the end of year 2000.
is a new wavelet-based image coding system for
different types of still images (bi-level, gray-level,
color, multi-component) with different characteristics
(natural images, scientific, medical, remote sensing
imagery, text, rendered graphics, etc.) allowing different
imaging models (client/server, real-time transmission,
image library archival, limited buffer and bandwidth
resources, etc.) preferably within a unified system.
This coding system is intended to provide low bit-rate
operation with rate distortion and subjective image quality
performance superior to existing standards, without
sacrificing performance at other points in the rate-distortion
This standard will serve still image compression needs
that are currently not served by the JPEG standards.
For example, very low bit-rate, progression for the WWW,
medical imagery, pre-press, etc. It is intended to complement,
not to replace, the current JPEG standards. Indeed, this
standard is expected to include an architectural context
that will allow the previous standards to be used as desired
on different tiles and/or components within a single image.
